Debugging ONMIBUS cards

The inchworm program is about as far as I can get without custom-crafting diag routines until I get a TTY online to read MAINDEC tapes. At the moment, all I have in the -8/e is the CPU, an MS8-C and an M8650. I toggled in an ASCII printing routine from the 1973 -8/e handbook (page 4-4, IIRC) and I didn't see anything appear on the terminal nor the RS-232 traffic light. If you happen to have a handy TTY test loop up your sleeve, then I'd love to see it. It makes it much harder to debug hardware when you have to debug your own diagnostic software at the same time. I'd still love to hear why a KK8A isn't happy with the -8/e frontpanel. I would have thought that they were compatible. The OMNIBUS isn't all that complex. There's not a lot of room for variations. Here's the problem... I can only test so much of the -8/e with only the front panel and the docs I have (I don't have a sheaf of toggle-in diags to try or I would). Once I put the KK8E in the -8/a box, _all_ I can do is hit the boot switch. It doesn't boot. The KK8A sort-of boots. There's this enormous testing gap between what I can do on the -8/e with no ability to load in diag tapes and what I can do on the -8/a with only the OS to boot. If I at least had an -8/a front panel, I could do some testing in that frame as well. Beyond a possible dirty EXAM switch, I have no reason to suspect anything is wrong with the 8/e front panel. A secondary question: when WPS throws up the "ABC" at the start of the boot sequence, what happens between the letters? I have one disk that only shows the "A" and the CPU locks up. What might that suggest? Thanks, -ethan ===== Infinet has been sold. The domain is going away in February.
